Abstract

A venipuncture and cutaneous sealing device and method which permits the capturing of a needle along its length either before or after a venipuncture, the engaging of the venipuncture site, and the sealing of both the puncture site and the needle tip. The sealing device may include two separable parts which are positioned along the length of the needle prior to the venipuncture. A split is provided in the sealing device to permit this capturing of the needle along its length or the sealing device may be pre-mounted on the needle along its length. The sealing device is slid or pressed into engagement with the skin at the venipuncture site and the needle is then withdrawn from the puncture site thereby leaving one part of the sealing device on the puncture site to seal the puncture site and absorb any blood at the site. Further, the other part of the sealing device is left on the needle to seal the tip of the needle and absorb any blood on the needle. The venipuncture and cutaneous sealing device prevents or substantially minimizes the possibility of patient blood coming into contact with the nurse, doctor or technician who is extracting blood from the patient. The sealing device may include a cover or shield which provides an additional barrier between the doctor, nurse or technician who is extracting blood and the absorbed blood within the sealing device.
